Hello Talkingreef members, I'm looking to buy a better quality timer to control my Calcium Reactor's on/off state. I'm curious to know what are everyone's thoughts and personal experiences with the Hamilton 24 Hour Digital Timer. I understand that you can set this timer presets down to the minute which make integration with my Calcium Reactor a definite must. Your assistance is greatly appreciated.

I'm struggling with the concept of why you wish to turn your reactor off? At what time during the day does your calcium draw decrease???

Salt Rookie, all the reasoning behind turning of the Selonoid to stop the introduction of CO2 is explained in this thread below:

You're quite right. The only thing that gets shut off is the CO2 solenoid. The reactor recirc pump and the feed pump should never stop.
